v Application filed may 23,

My invention relates toimprovements in heaters, and more particularlyhas reference Fig. 2 is a cross-section on Fig. 1, and Fig.

3 is a section on the line-8-3 of Fig. 2 looking from left to rightthereat. I a

4 indicates the base or table of the heater, and 5 a suitable channel orrecess in which the radiant or blocks of refractory material areremovably mounted. 6 indicates a removable. channel for the support ofthe grilles adapted to stand in front of the radiants, and said channelis preferably provided with key-shaped end portions such as 7 adaptedtoseat within the recess 8 at opposite ends of the table as shown.Between and substantially below the channels 5, 6 are the burnerchambers 9 provided with substantially triangular mixing chambers asshown and grids 10 through which the mixture passes to be burnt. 11indicates the Bunsen burner tuberonnected to said burner chamber andpreferably terminates with. a flareend 11 adaptedto be seated inthebifurcated or V- shaped .member 12' shown to advantage in Fig. 3, astop"men1ber13 being provided to engage the periphery of the enlargedend 11 for insuring proper positioning ofthe burner. At the oppositeside of the table prongs or lugs 14 extend and are provided withseatingssuch as 15 or depressions between the enlarged portions 16, 17andthe burner is preferably beveled or rounded as indicated at 18 toengage the seating .15

and is also preferably provided with teats.

or buttons 19 adapted to bear against the front surface 20 of thechannel 5 to further insure the proper positioning of the burner, fromall of which it will be seen that the burner may be placed in positionas shown without disturbing any parts except the hearth plate or shelf21 which may then be placed in position, the depending flange 22 thereofhaving cut-away portions such as 23 to clear the Bunsen tube 10 of theburners, said flange 22 serving as a wind guard. The lugs such as 24Lproject upwardly from the casting or table 4 at op- HEATER.

posite sides and engage the ends of the hearth shelf to keep the samefrom shifting from side to side while the lug 25 extending from theunder frame of the hearth table 21 engages the inner surface of themanifold or rectangular gas channel 26, thereby preventing the hearthtable from movingfout from the heater. This hearth table consistspreferably of a frame such as 21 provided with such as 28 of 'tileorother suitable material which may be sealed with cement such as 29 orother suitable hermetical binder.

From the foregoing it will be obvious that the shelf or hearth 21 may beconveniently removed, likewise the channel 6 after the grilles have beentaken away, and alsothe spuds 30 which are adapted to be screwed in thegas. channel 26'as shown to advantage in Fig. 2. u

The grids 10 it will be observed are beveled along the longitudinalsides so that they may be slid into and out of the open mouth at the topof the burner head 9, and when in position may be locked therein by Vtransverse connecting members orstraps 27 upon which may be securedslabs pinching. the ends of the walls 31 of the burner niouth as shown.These grids may of course be secured 111 other ways such asby a pin, andgrids with openings of different 'newablein parts, convenient forshipment and simple for manufacture.

Of course it will be understood that vari ous modifications may be madein theconstruction and arrangement of parts without departing from thespirit of the invention as claimed.

I claim:

1. In a heater of the class described, a base section having a removablehearth, a removable grille holder back of the same, and re movableburnersbeneath said hearth.

2. In a heater of the class described, a hearth section having aremovable shelf, a removable grille holder back of the same,

and removable burners beneath said shelf, and in combination therewithpositioning means for insuring the proper location of each of saidburners.

3. In a heater of the class described, a base section having an openportion in which burners may be seated, each of said burners comprisinga tube spanning said open portion, and a burner head at one end of saidtube, said burner head having aremovable grid in the upper end of theburner head connected to said tube.

4. In a heater of the class described, a hearth section having an openportion in Which burners may be seated, each of said burners comprisinga tube spanning said open portion, and a burner head at one end of saidtube, said burner head having a removable grid in the upper end of theburner head connected to said tube, a manifold adjacent the other end ofsaid tube and removable spuds projecting therefrom adjacent said otherends of said tubes.

I 5.'In combination with a heater of the class described, a front basemember having a substantially central cut-away portion, a removablehearth adapted to be seated thereover, and burners adapted to be'removably retained beneath said hearth.

6. In combination with a heater of the class described, a front basemember having a substantially central cut-away portion, a removablehearth adapted to be seated thereover, and burners adapted to beremovably retained beneath said hearth. and in combination with saidbase member means for positioning said burners.

7; In combination with a member of the class described, a front basemember having a substantially central cut-away portion, a emovablehearth adapted to be seated therever, and burners adapted to beremovably 'sretained beneath said hearth and a removhearth.

9. In combination with a heater of the class described, a front basemember having a substantially central cut-away portion, a removablehearth adapted to be seated thereover, and burners beneath said hearth,said hearth having a wind guard. A

11. In combination with a heater of the class described, a front basemember having a substantially central cut-away portion, a removablehearth adapted to be seated thereover, a fuel manifold in front of saidbase member, and burners across said cut-away portion.

12. In a heater of the class described, burners extending fore and aftof the same and in front of the radiants thereof, and means incombination With the frame-Work of said heater and independently of saidburners for positioning the same.

13. In a heater of the class described, a base section having aremovable hearth, a grille holder back of the same, and removableburners beneath said hearth.

14.,In a heater of the class described, a base section having aremovable hearth, a grille holder back of the same, and burners beneathsaid hearth.

15 In a heater of the class described, a base section having an openportion in which burners may be seated, each of said burners comprisinga tube and a burner head at oneend of said tube, said burner head havinga removable grid in the upper end of the burner head connected to saidtube.

16. In a heater of the class described, a hearth section having an openportion in which burners may be seated, each of said burners comprisinga tube and a burner head at one end of said tube, said burner headhaving a removable grid in the upper end of the burner head connected tosaid tube, a manifold adjacent the other end of said tube and removablespuds projecting therefrom adjacent said other ends of said tubes.
